That's not what I was saying. I wasn't saying "work on it overnight". In fact, nowhere in my post did I even allude to that. If something on a ride breaks, I would think it might be easier to shut down the ride for a few days and fix it, rather than continue operating the ride, which would allow other things to break on the ride at which point the ride has to be closed for weeks or months to repair. By repairing as needed, it gives more guests a chance to still be able to enjoy the ride, since it would have a possibility of being open at least once during their trip.
